Perfect for the potted container, this variegated form of the semperflorum begonia brings diversity in color as well as vigor to the windowsill or light garden. The “Calla’s” leaf color changes with light intensity; brighter light and longer days bring out red tones and stronger variegation. The plant stays small, under 8″ and loves any sunny exposure. This traditional indoor plant tolerates a dry atmosphere and does well even with irregular watering, preferring some soil dryness.
